Global Defense for the SEGA Master System is a unique retro game from the 80s where you control a satellite battling enemy missiles and satellites. Each stage is divided into two parts: an offensive sequence as a classic side-scrolling shoot ’em up, and a defensive sequence inspired by Missile Command.

The player controls both the satellite’s movement and aim, creating a more tactical experience. Destroy all enemies in the offensive part, and the defensive stage is skipped. A perfect playthrough even rewards you with a hidden Easter egg.
